A mid-ripening variety with early bud break. The vines are of medium vigor; leaves are medium or large, three- or five-lobed. Flowers are hermaphroditic. Clusters are medium, conical, often winged, medium-dense or dense. Berries are round, white-yellow in color, medium-sized, covered with firm, thick skin and have juicy pulp.
Yield is 90–110 c/ha. Shoots ripen well, and the variety shows comparative drought tolerance and adaptability to soil types. Winter hardiness corresponds to the level of other European Vitis vinifera varieties. The variety requires regular preventative treatments, as it is sensitive to downy mildew and Eutypa dieback.
